Figure 4

Photomicrographs showing blood vessel distribution on scar tissue in Wistar rats. C1 = control 1—water via gavage and standard chow diet; C2 = control 2—water (no gavage) and standard chow diet; AL = alcohol—water (no gavage), alcohol (40%) via gavage and standard chow diet; HF = high-fat—water (no gavage) and high-fat diet (50%); HF + AL = alcohol/high-fat—water (no gavage), alcohol (40%) via gavage and high-fat diet. F0 = intact tissue; F1, F2, and F3 = scar tissue after 7, 14, and 21 days, respectively. Bar: 20 μm. HE staining.
